HVAC in Markham: what to expect
Markham mixes heritage and recent growth more sharply than most GTA cities. Unionville and Old Markham Village have 19th-century houses and early 1900s infill, with character details that make duct routing and equipment placement fussy. A few kilometres away, Berczy Village, Cornell, Angus Glen and Milliken are mostly 1980s to 2010s: better-insulated houses with sizeable mechanical rooms in the basement and builder-selected equipment.
Newer, tighter houses are worth considering for heat pumps because they can often be heated at lower supply temperatures. In practice the same questions apply to most houses. Does the house need a load calculation (yes), is the electrical service big enough for a heat pump and possibly an EV charger, and would a hybrid with the existing furnace make more sense? Markham's Highway 7, Woodbine and Warden employment areas add offices, flex units and light industrial space with roof-mounted equipment. Where electrical work is needed, Kelvin Mechanical works with licensed and qualified professionals and trade partners, depending on the project scope.

What Markham homes usually need
Heat pump or hybrid: check the house first
Whether a ducted heat pump, ductless heads or a hybrid with your furnace fits depends on insulation, air leakage, duct condition and how you heat today. Performance varies by model and operating conditions, so we assess the house before quoting. See heat pump installation for the steps.
Heritage cores in Unionville and Old Markham Village
Old houses rarely have a convenient place for large ducts. Careful routing, smart thermostat control and room-by-room zoning can improve comfort without cutting into original plaster and trim. Where outdoor equipment sits matters too, as heritage streets can have their own rules.
Flex units, offices and rooftop equipment
Many Markham business units are small enough to run on one or two roof-mounted systems, and failures tend to arrive during the first heat wave or cold snap. A seasonal visit covering filters, drains, belts and controls is easier than an after-hours repair; rooftop unit service covers the details.

Questions from Markham customers
Are there Ontario rebates for a heat pump in Markham?
Ontario's Home Renovation Savings program is delivered by Save on Energy and Enbridge Gas with support from the Ontario government, not by the city. Eligible Ontario customers may qualify for up to $7,500 depending on the program rules, equipment, property and funding available at the time. Check rebate eligibility first, because it can affect which equipment makes sense.
Will my electrical panel handle a heat pump and an EV charger?
Maybe. It depends on the panel rating, your existing loads and what a load calculation says. A panel and circuit review should come before equipment is ordered, and permits and ESA notification are handled where required.
Can you maintain rooftop units for a Markham office or flex unit?
Yes, within light commercial scope. We ask for the unit make and model, roof access and how the space is used, then suggest a maintenance schedule after a site review. Frequency and scope depend on the equipment.
Do you repair heat pumps and air conditioners in Markham, including units from other installers?
Generally yes, depending on the model and parts availability. We check the outdoor unit, indoor coil, controls and airflow, tell you what we find and whether a repair makes sense. A diagnostic fee may apply; confirmed at booking. Emergency service is subject to availability. See heat pump repair and AC repair.
